SUMMARY:Massive holomorphicity in near-critical dimers and the Sine Gordon
  model - Nathanael Berestycki (University of Vienna)

DESCRIPTION:We consider the near-critical dimer model on isoradial graphs\
 , with Temperleyan boundary conditions. We show that the centered height f
 unction converges as the mesh size tends to zero to a limiting field which
  agrees with the (electromagnetically tilted) sine-Gordon model at the fre
 e fermion point. This answers a longstanding question in the field. A cruc
 ial part of the work is to develop a notion of massive holomorphicity both
  in the continuum and at the discrete level.
